Unless you're from the planet Krypton, you've most likely been sick at some point. And while going to the doctor is a bummer, you probably appreciated the nurse who took the time to make you feel at ease. Nurses are in high demand, both in hospitals and private home care—but because the work is challenging, you need to have real passion for the job. As a nurse, you'll have to administer medical tests, draw blood, fill out charts, and assist doctors in any way needed—and you're also there to keep patients from getting consumed by anxiety. So if you think you've got the right personality, then get yourself the training to have a career in the booming healthcare industry.
